What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline (Average of Screening and Day 0) in the Average TMC Scores From Weeks 9 & 12
Time Frame: Screening, Day 0, Weeks 9, 12
Total TMC score is a sum of chorea scores which range 0-28, with a decrease indicating improvement in chorea
Screening, Day 0, Weeks 9, 12

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Participants With Treatment Success at the End of Therapy as Measured by the Patient Global Impression of Change (PGIC)
Time Frame: 12 weeks
A treatment success is defined as Much or Very Much Improved at the Week 12 visit. The PGIC is a 7-point Likert Scale, ranging from very much worse to very much improved
12 weeks
Number of Participants With Treatment Success at the End of Therapy Based on Clinical Global Impression of Change (CGIC)
Time Frame: 12 weeks
A treatment success is defined as Much or Very Much Improved at the Week 12 visit. The PGIC is a 7-point Likert Scale, ranging from very much worse to very much improved. The clinician was asked to comment about the subject.
12 weeks
Change in the Short Form 36 Health Survey (SF-36) Physical Functioning Score (Based on Items 3a to 3j) From Baseline to Week 12
Time Frame: Baseline, 12 weeks
Change in the Short Form 36 Health Survey (SF-36) physical functioning score (based on items 3a to 3j) from Baseline to Week 12. The lower the score the more disability. The higher the score the less disability i.e., a score of zero is equivalent to maximum disability and a score of 100 is equivalent to no disability.
Baseline, 12 weeks
Change in Berg Balance Test (BBT)
Time Frame: Baseline, 12 weeks
The Berg Balance Test (BBT) is a 14-item assessment of sitting, standing, transferring, and turning. Each task ranging from standing up from a sitting position, to standing on one foot each task is given a score of zero (unable) to four (independent), and the final measure is the sum of all of the scores.The scale range, which is 0-56, with higher scores indicating better balance/lower fall risk.
Baseline, 12 weeks
